`| MPRovEM ENT IN GAs- HEATERS.

Specification forming part of Letters PatentNo. 78,951, dated June 16, 1868.

To all whom it may concern:

Be it known that I, OSCAR (l. FOX, of Georgetown, in the District of Columbia, have invented a new and Imprpved Petroleum-Gas Stove; and do hereby declare that the followm g is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.

Figure 1 shows the structure with casings removed. Fig. 2 is a perspective view of the stove in working order. Fig. 3 is a section of the stove cut in the plane of the rire or gener- Fig. 4 is the crown or cylinder.

To enable, others skilled in the arts to make and use my invention, I will proceed to describe its construction and operation.

I construct my stove in any approved form, and of the most suitable material. Its interior is arranged so as to most effectually secure The fire-plate A centers over the burner B.`

Its lower surface is made convex, a form best adapted to evenly radiate the heat. This is surrounded with metal tube or cylinder E, which may be made a part of or securely iitted to the bottom plate of the stove, and reaching upward something more than one-half the distance between the top and bottom, and of a diameter adapted to the size of the stove, and such that an article of furniture placed in the hole of the stove may rest upon the crown of the cylinder or come within its walls. The top of the cylinder I cut in notches o o o, furnishing apertures for the lalne and heat to pass out and around the furniture placed in the stove. The fire-plate Ais of less diameter than the cylinder, leaving space between them for passage ofthe ame and heat as thrown of the fire-plate.

rIhe oflice of the cylinder is twofold. It radiates and reflects the heat and iiame thrown off by the iire-plate A, bringing it in direct Gas-stoves now in use become worthless when this pipe is burned out, as it always is sooner or later, there being no way of removing the old and substituting new.

By thus constructing the generating-pipe I am also -enabled to remove the re-plate A when worn or broken, and `substitute a new one. The fire-plate is secured to the generating-pipe by a loop passing over it, and firmly held by a thumb-screw, M, or other eiicient means.

The generating-pipe is carried through the flue or cylinder, and, passing down through the bottom plate of the stove, is brought to the point for the attachment of the burner B.

My burner I construct with a shield or cup, I

G, of sulicient dimensions to receive all waste oil, and in such proper distance from the top of the burner that the refuse oil, falling within it, is' readily burned.

With my burner I dispense with all receptacles for receiving the waste oil, as by my process there is, in fact, no waste oil or drippings.

I construct my stoves with one or more burners. When I have more than one I insert a movable slide, K, by the means of which one burner may be used, and all the heat retained in that part of the stove. The stove is supported by legs d d d d.

Its operation is simple. The benzine or other inllammable substance is admitted into the generating-pipe by turning the cock W.

(The supply is regulated bythe cock W.) The fluid passes through the generating-pipe to the burner B, where it is ignited by extending the lighter under the stove; Ifhe iiame heats the fire-plate and-generating-pipe, and as they become hot the iluid is converted into gas, and the ilame is fed by gas alone. i

The generatingpipe is connected with the supply-pipe N, at X, in any convenient manner. My stove may be also used with common gas. It is only necessary to connect the generating-pipe with the gas-fixtures, and it is ready for operation.

- The advantages of my stove over others con'- sist in its simplicity, cheapn ess, and durability, as well as its adaptation to use common gas, or any liquid which can be converted into gas by the application of heat.

WhatI claim as my invention7 and desire to secure by Letters Patent, is

l. A petroleum-stove having the detachable ypipe L, burner B'cup C, and cylinder E, the

upper edges of which are notched, al1` con'- structed and arranged substantially as shown and described.

2. A stove having two or more compartments, provided with independent burners,

and havingyan adjustable slide for separating said compartments, whereby either 'may be heated and used independently of the other, I

when constructed'and arranged substantially as herein set forth.
